Idunella sketi

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Idunella sketi faces severe threats from groundwater pollution and contamination of its cave aquifer systems. The species' extremely restricted range in underground karst environments makes it particularly vulnerable to chemical runoff from agricultural activities and urban development above ground. Water table alterations from mining operations and excessive groundwater extraction further threaten the delicate hydrological balance required for this cave-dwelling species' survival.

Threat summary

Habitat

Idunella sketi inhabits underground freshwater cave systems and karst aquifers in the Dinaric Alps region. This highly specialized species is adapted to the stable, dark conditions of subterranean water bodies with specific temperature and chemical parameters.
